MUTE non WIND INSTRUMENTS.

Application lled July 3,

To @ZZ lwhom t may concern,

Be it known that I, VILLIAM A. MoAr.` 'ri-Ter., a citizen of the United States of America, residing at Ferndale, Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in llistes for lVind Instruments, of Which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to mutes for Wind instruments and particularly for cornets and the. like,

It is an object of the invention to provide an attachment for ccrnets and similar instruments which Will so modulate the tone as to secure close simulation of a French horn.

A further object is to form such an attachment With spring arms that may be snapped into engagement With the bell of a horn to accomplish a secure yet quick detachable mounting of the device on the horn.

Another object is to provide a mute attachment for horns Which When not in use may be telescoped over the bell of the horn.

ln the drawings Figure l is perspective view of the attachment 5 Figure 2 is sectional vien7 of the same engaged with the bell of a horn,

ln these vievvs the reference character rdesignates a sleeve formed preferably of rolled sheet fiber, one end of said sleeve being closed by a disk of the same material, as indicated at B, and a plurality of arch shaped openings C being extended from the other end, arms l) being formed between said openings. Said arms constitute supports for the device, their free ends being transversely channeled, as indicated at E, for engagement ,vita thc bell of a cornet or other horn F. Illhe material comprising the sleeve A is sufficiently resilient that through noper prcportioning` of said sleeve, arms may be adapted to engage the bell of the horn under tension, so as to hold the attachment quite securely in its position of use. Preferably each of the arms D is reinforced by a slight longitudinal bead F. Preferably mounting of the end plate B is accomplished by forcing the saine into an annular bead G provided in the member A. It has been found desirable to reinforce each of the spring arms l) terminally by a metal plate H exteriorly applied and conforming 1922. Serial N0. 572,741.

to the curvature of said arm, said plates being held in place by rivets I. rlhe space J formed Within the sleeve A between its closed end and the openings C functions as a sound chamber and is highly important in obtaining the desired tone effect. The specilied material (sheet. fiber) employed to form the device is also a factor in obtaining the desired tone. By dash lines in Figure 2 is indicated the stored posit-ion of the device with respect to the bell of the horn F, the latter being telescopically embraced by the sleeve A in said position.

It is a feature of the construction that the spring arms D adapt the device to be mounted quite firmly upon the bell of the horn maintaining engagement therewith Whether or not the horn is in position of use or any other position. The described mounting, however, is of a quick detachable nature since a slight manual effortvvill disengage the spring arms from the horn.

The tone resulting from the use of the described attachment is very smooth and clear and not distinguishable from the tone ordinarily produced only by a French horn.

It is to be noted that the arms D, are sprung slihtly toward the axis of the attachment so that the bell of the horn terminally embraced by said arms may have a lesser diameter than that of the sleeve A. Thus clearance for the bell of the horn Within said sleeve in stored position of the latter is assured.

1What I claim as my invention is l. A mute attachmentfor horns comprising a sleeve of fibrous material substantially closed at one end and formed at its other with resilient arms proportioned for snap engagement with the flared end of a horn.

A mute attachment for horns comprising a sleeve having a larger diameter than the. bell of a horn and being substantially closed at one end. said sleeve being formed at its other end with openings for the egress ol sound vibrations? between integral resilient arms detachably embracing the bell of said horn.

3. i mute attachmentfor a horn including a sleeve closed at one end, and means projecting forwardly from the open end of said sleeve for detachably securing the same to said horn, said sleeve having a greater diameter than the bell of said horn whereby said sleeve may receive the bell of said horn.

4. A mute attachment forl a horn comprsing a sleeve provided at one end with a ing the bell of said horn, the other end 01 lateral opening and integral vresilient supszidsleeve hemgtclosed, the diameter of the 0 porting arms, the other end of said sleeve sleeve being slightly greater than that of the being substantially closed, and metal plates bell of said horn whereby said sleeve may 5 reinforcing said arms. telescopoallyembrace said bell.

5. A mute attachment for a horn Comprslntestmony whereof I afx my signature.

mg a sleeve provided at one end with a latv eral opening, and arms detachably embracl I VILLIAM A; MCARTHUR.
